associated re-labels bel ray oil. works great and is pretty easy to clean. I mean, cliff lett worked for honda or was it yamaha?

I use the PJ1 motorcycle filter oil. It's sticky as hell and does whats it is supposed to.

SWAFF Rock oil...TKO its great stuff.

i use the losi pre oiled filters. when im finished i just throw them away and buy new ones. usualy replace them after each race day. with a little grease on the ends their is no way for dirt to get through them. i used the rock oil before that. it worked good also.

pj1 foam filter oil in a spray can it lasts forever and only cost 8 bucks. The cleaner goes faster so use a zip loc bag to clean them in. I pick up the dirty filters at the track clean them and hand them out like candy the next week. I haven bought filters in years because so many people toss them out.
